摘 要
   随着时代不断的发展钢铁行业向着高速、重载、运载能力的跨越式发展。好多生产车间的工作量以及效率在不断加大和提高，这样对车间的物流速度要求也有了进一步提升。先前靠单一的天车来搬动工件已经完全不能满足现代高效率的生产要求，同时这种大马拉小车的搬运方式也成为了一种典型的浪费。因此车间内需要这种具有结构简易、承载能力大、使用方便、、容易保养、使用寿命长得料斗小车来保证搬运的畅通，我所设计的料斗移动小车就完全适应社会的需求。
    我设计的料斗移动小车又叫过跨电动平车，在经过大量阅读料斗小车书本的基础上，我从小车生产需求方面出发，设计了50T的电动平板车样机。                             关键词：平板车 强度 轨道车轮

Hopper electric flat car design
Abstract
  With the development of the era constantly steel industry towards high speed, overload, leapfrog development capacity. A lot of work and efficiency of production workshop in growing and improving, so logistics speed requirements of workshop has a further increase. Prior to move the workpiece by a single crown has been completely can not meet the requirement of the modern high efficient production, at the same time the large mara car handling way has also become a kind of typical waste. So the workshop need this has simple structure, convenient use, large carrying capacity, easy maintenance, long service life of the hopper electric flat car to ensure smooth handling of so I designed hopper electric car was completely adapt to the demand of the society.
I've designed hopper car is primarily a cross electric flat car, after extensive reading on the basis of related literature, I based on actual production demand, the 50 t electric flat car prototype design.
I have mainly introduced the cross in the design of electric flat car overall design theory and design process, including a across the overall design of electric flat car running mechanism and transmission mechanism, across to the layout of the electric flat car body, car running mechanism calculation. Calculation in the design of shaft and bearing selection, the selection and design of the bearing, gear motor selection, the design of the shaft.
